Kuettlingeria erythrocarpa is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae.

[2] It was first scientifically described as a new species in 1810 by the mycologist Christiaan Hendrik Persoon, who named it Patellaria erythrocarpa.

In 2020, lichenologists Ivan Frolov, Jan Vondrák, and Ulf Arup transferred the taxon to the genus Kuettlingeria.

[4] Kuettlingeria erythrocarpa is predominantly found in the Mediterranean region and extends into the warmer areas of the sub-Mediterranean belt.

It favours horizontal to slightly inclined surfaces that receive rainfall, thriving particularly in natural habitats at lower elevations.
